//! Filesystem helpers that preserve path context in `SpliceError::Io`.
//!
//! `From<std::io::Error> for SpliceError` produces a `SpliceError::Io` with
//! `path = "<unknown>"`, which loses information for the user. These helpers
//! wrap the common `std::fs` operations so the originating path is captured.
